Water Rats

The Sydney Water Police investigate a fatal bombing on a charter ferry while trying to locate other explosive devices that may still be located in the harbour. The Nemesis crew scrambles to recapture a murder suspect who escapes custody. Kevin Holloway, Frank's younger brother, joins Homicide and is partnered with Frank's good friend Knocker Harrison. A man claiming to have the missing bomb takes hostages on a passenger ferry. Frank and Rachel stake out a yacht to catch a scantily clad burglar. A diver dismissed from duty dives the site of the ferry wreck to locate the fourth bomb in order to eliminate the hijackers threat. Frank's older brother Jimmy is released from prison two years after Frank put him away as part of a drug bust.

Back on deck after having shot her fiancé corrupt copper, John ""Knocker"" Harrison dead, is Detective Rachel ""Goldie"" Goldstein, reacting snappily to being dubbed ""Gunner Goldstein"" by a colleague with an unhealthy interest in what it's like to kill someone. Dave McCall is at the receiving end of a spear from a sunken and booby-trapped car, loaded with stolen gold ingots. Goldie and Frank Holloway investigate a bouillion robbery. The ""Nemesis"" crew are looking after a prisoner, a former Olympic rowing champion.

Franks second ex-wife, Liz Robinson, seeks his help and protection from a blackmailer who has photos of her having cocaine snorted from her naked belly. Tayler Johnson and Gavin Sykes have to deal with some prisoner escapee.

The Water Police are plagued by a series of hoaxes and it is up to Frank and Goldie to determine who and what they can trust.

The series resumes on a spectacular note with a helicopter crashing into an overcrowded pleasure boat. The fatality list is long but two survivors are trapped on the sinking craft unable to be moved. Meanwhile, on shore, Mary Coustas (without the Effie frightwig) is a troubled survivor and knows more than she is saying. There is a scramble for clues as the detectives Jack Christey and Alex St Clare track down the cause of the chopper's crash and ponder why the pilot has a bullet wound in his neck. It's a good yarn and the drama, as Tommy Tavita and his mates work to save the trapped souls, is tense.

A water police operation on a container wharf results in a death, leaving each of the Rats to deal with their culpability and guilt.
